Frequently Asked Questions

Will these work with stock Harley compression releases?

No — S&S compression releases are starter-relay controlled, while stock HD automatic compression releases (ACR) are ECM-controlled and are not compatible. Do not attempt to wire them together, as this will damage the heads and engine.

What compression ratio do these heads deliver?

The 89cc combustion chamber provides slightly higher than stock compression, making them ideal for larger stroker and big-bore engines while remaining manageable for touring applications.

Can I use these on a stock-displacement engine?

Yes, they work on stock-displacement engines, but they are optimized for stroker or big-bore applications up to 110 cubic inches.

Do these heads require a stock crankcase?

Yes — these heads are designed specifically for engines with stock crankcases.
